Clinical characteristics of firearm-related injuries in children in Turkey.

BACKGROUND: A significant number of children are injured by or die from firearm-related incidents every year, although there is a lack of global data on the number of children admitted to pediatric emergency departments (PEDs) and pediatric intensive care units (PICU) with firearm injuries. This study is the most comprehensive analysis of firearm injuries sustained by children in Turkey to date. METHODS: This multicenter, retrospective, cohort study was conducted between 2010 and 2020 with the contributions of the PEDs, PICUs, intensive care units, and surgery departments of university hospitals and research hospitals. RESULTS: A total of 508 children were admitted to hospital with firearm-related injuries in the research period, although the medical records of only 489 could be obtained. Of the total admissions to hospitals, 55.0% were identified as unintentional, 8.2% as homicide, 4.5% as self-harm, and 32.3% as undetermined. The Glasgow Coma Scale (GCS) and ventilation support were found to be the most significant predictors of mortality, while head/neck injury, length of stay (LOS) in the hospital and surgical interventions were found to be the most significant predictors of disability. The overall mortality of firearm-related injuries was 6.3%, and the mortality for children admitted to the PICU was 19.8%. The probability of disability was calculated as 96.0% for children hospitalized with firearm injuries for longer than 75 days. CONCLUSIONS: Head/neck injury, LOS in the hospital, and surgical interventions were found to be the most significant parameters for the prediction of disability. Hospitalization exceeding 6 days was found to be related to disability.

Evaluation of oxidative stress in children with congenital heart defects.

BACKGROUND: A significant cause of death and chronic illness in childhood is caused by cardiovascular diseases, including congenital heart disease (CHD). This study aims to investigate the oxidative stress status and to establish its association with CHD in children. METHODS: The study involves measurements of malondialdehyde (MDA), protein carbonyl (PCO), total anti-oxidant capacity, high-sensitive C-reactive protein (hs-CRP), fibrinogen and cytokine (interleukin [IL-6] and tumor necrosis factor-α) levels in 43 children with CHD and 30 healthy age-matched children. RESULTS: MDA, PCO, hs-CRP, fibrinogen, IL-6 and tumor necrosis factor-α were significantly elevated while total anti-oxidant capacity was significantly declined in patients compared with the controls. MDA was positively correlated with PCO, hs-CRP, Qp/Qs and systolic pulmonary artery pressure. PCO was positively correlated with hs-CRP, fibrinogen, IL-6 and systolic pulmonary artery pressure. CONCLUSION: Oxidative stress and its association with other markers in children with CHD was established. To the best of our knowledge, this is the first time that PCO has been used as a biomarker in CHD and it may be employed as a new diagnostic biomarker in CHD and in the assessment of its severity.

Postnatal management of infants with antenatally detected hydronephrosis.

With the increasing use of antenatal sonography, fetal hydronephrosis has been reported more frequently. Because of the lack of consensus regarding treatment of these infants, the postnatal approach toward fetal renal pelvis enlargement remains controversial. The aim of this prospective study is to demonstrate the postnatal investigation, treatment, and outcome of infants with prenatally diagnosed hydronephrosis. Infants whose antenatal ultrasound scan showed a fetal renal pelvis of 5 mm or greater were investigated postnatally using ultrasound (US) and voiding cystourethrography. When indicated, isotope studies and intravenous urograms were also performed. We followed prospectively neonates with antenatally diagnosed hydronephrosis and recommended management guidelines on the basis of our findings. In 156 neonates (193 kidney units) that were found to have hydronephrosis, the average gestational age at which the diagnosis was made was 32.94+/-5.10 weeks. The mean duration of postnatal follow-up was 26.3+/-13.56 months (range 3-60 months). The mean APPD of the fetal renal pelvis was 10.35+/-3.24 mm (5-9 mm in 84 kidneys, 10-14 mm in 96 kidneys and > or =15 mm in 13 kidneys). Of the 193 kidney units, 145 units were found to be pathological. The most common detected underlying abnormalities were ureteropelvic junction obstruction (in 91 kidneys; 62.7%) and vesicoureteral reflux (in 24 kidneys; 16.6%). Postnatally, 23 (45%) of 51 patients whose first US was normal were diagnosed postnatally as having urinary tract abnormality. There was a negative correlation between APPD and the rate of spontaneous resolution and positive correlation between APPD and the rate of surgery (P<0.01). In conclusion, because it is not possible to determine an upper limit of normal for the antenatal renal pelvis, any baby with AH should not be considered clinically insignificant. Infants with antenatal renal pelvis measurements > or =5 mm should be investigated postnatally. A normal postnatal ultrasound scan does not preclude the presence of urinary tract abnormality.

Percutaneous nephrostomy in children: diagnostic and therapeutic importance.

The aim of this study was to evaluate the effectiveness and safety of percutaneous nephrostomy (PN) in terms of diagnostic and therapeutic approach in children with urological problems. PN was performed on 39 kidneys in 28 patients (12 girls, 16 boys) aged 4.5 months to 13 years (average 5.38+/-3.41 years) during the period from January 1996 to December 2003. Underlying abnormalities were ureteropelvic junction obstruction (UPJO) in 14 patients (17 kidneys), ureterovesical junction obstruction (UVJO) in six patients (eight kidneys), supravesical obstruction due to tumour or hydatid cyst or ureteral stone in three patients (five kidneys), and severe vesicoureteral reflux (VUR) with/without neurogenic bladder associated with pyonephrotic kidneys in five patients (nine kidneys). The duration of catheter insertion was between 2 and 160 days (average 80+/-65.01 days). The complications were haematuria (six cases), infection (five cases) and displacement of catheter (four cases). Radical surgical management was performed in 25 patients (33 kidneys): pyeloplasty in eight cases (ten kidneys), UVJO correction in six cases (eight kidneys), nephrectomy in five cases (five kidneys), ureteroneocystostomy in four cases (seven kidneys), hydatid cyst operation in one case (two kidneys) and stone extraction in one case (one kidney). PN is an easy, safe and efficient diagnostic and therapeutic procedure with few complications in childhood.
